Currently, customers with either landlines or cellphones, have to opt in to the call blocks, USA Today reported.

The rule would allow companies to put into practice controls that many have already developed but haven’t rolled out because they were afraid the measures used to block calls would be considered illegal, CNN reported.

“Allowing call blocking by default could be a big benefit for consumers who are sick and tired of robocalls,” FCC Chairman Ajit Pai said in a statement.

The FCC is also looking into verifying the phone numbers that appear on caller IDs. Many scammers are spoofing numbers, using local area codes to get unsuspecting phone users to pick up a vaguely familiar number, CNN reported.
